Klopp has been praised this season for his use of subs, but the reason he has to make wholesale changes every match to rescue games is that not one of the front lads we have are consistant in any way, or the midfield. Macca maybe, but that's literally it.
So every single game he's having to throw on 3-4 subs to try and save a match, and usually it's worked, but last night looked desperate. In a cycle of picks a front three, they don't perform from the start, he has to throw on 3 subs, they play well, they start the next match, are shite, and he has to trow on three subs again, who play well, and then start the next match ... etc etc ad infinitum.
Last night looked the culmination of that, only this time the lads he's throwing on to rescue it are as bad as the ones he's took off the pitch.
Far, far too many of this squad can't put a run of games together were they perform, week in, week out. They are great one week, shite the next.
